In order to investigate, whether the EMT “master regulators” SNAI1 and TWIST1 and the mesenchymal marker CDH2 are already expressed in colorectal adenomas, we assessed their expression in formalin fixed and paraffin embedded (FFPE) tissues and used previously published primers and probes for a quantitative RT-PCR assay (qPCR) that were shown to work well in FFPE material [18]. This evidence concerns the gene TWIST1 and colorectal adenoma.
